io_uring: Change res2 parameter type in io_uring_cmd_done
Change the type of the res2 parameter in io_uring_cmd_done from ssize_t
to u64. This aligns the parameter type with io_req_set_cqe32_extra,
which expects u64 arguments.
The change eliminates potential issues on 32-bit architectures where
ssize_t might be 32-bit.
Only user of passing res2 is drivers/nvme/host/ioctl.c and it actually
passes u64.
